The discovery of a living species of coelacanth, a lobe-finned fish recognized as an important transition in vertebrate evolution, was a surprising and exciting find in 1938, because the fish was already widely recognized in the fossil record. Hailed as a living fossil, even though there has never been any fossil find of the two extant species of coelacanth, it is native to waters around Indonesia and in the Indian Ocean...
This simple game has deceptively difficult computational problems behind it, which might be why it’s so addictive.
Appearances to the contrary, no species is exempt from selection, even when changes are difficult to detect in the fossil record.
The blooms’ varied hues trace back to both soil pH and the right additives.
Could different combinations produce new tints never seen in nature?
Estradiol, the most common form of estrogen, is often called a female hormone, but men produce it too. Insight about its role comes from unusual sources.
Data-dependent analysis—a “garden of forking paths”— explains why many statistically significant comparisons don't hold up.
